Шаблон:Short description Шаблон:Infobox Computer

ESP32 is a series of low-cost, low-power system on a chip microcontrollers with integrated Wi-Fi and dual-mode Bluetooth. The ESP32 series employs either a Tensilica Xtensa LX6 microprocessor in both dual-core and single-core variations, Xtensa LX7 dual-core microprocessor or a single-core RISC-V microprocessor and includes built-in antenna switches, RF balun, power amplifier, low-noise receive amplifier, filters, and power-management modules. ESP32 is created and developed by Espressif Systems, a Chinese company based in Shanghai, and is manufactured by TSMC using their 40 nm process.[1] It is a successor to the ESP8266 microcontroller.

ESP32-xx family

Since the release of the original ESP32, a number of variants have been introduced and announced. They form the ESP32 family of microcontrollers. These chips have different CPUs and capabilities, but all share the same SDK and are largely code-compatible. Additionally, the original ESP32 was revised (see ESP32 ECO V3, for example).

In 2020, chips ESP32-D0WDQ6 and ESP32-D0WD also got a V3 version (ESP32 ECO V3), which fixes some of the bugs[16] and introduces improvements over the previous versions.

Modules

The ESP32 PICO system in package modules combine an ESP32 silicon chip, crystal oscillator, flash memory chip, filter capacitors, and RF matching links into a single 7 mm × 7 mm sized QFN package.

The first released PICO was the ESP32-PICO-D4 with 2 CPUs at 240MHz, 4MiB internal flash, a 40MHz oscillator and 34 GPIOs.[17]

Later, in 2020, the ESP32-PICO-V3 and ESP32-PICO-V3-02 modules were introduced both based on the ESP32 ECO V3 wafer.[18] [19]

In 2022 the ESP32-S3-PICO-1 module was introduced with USB OTG and internal PSRAM.[20]

  • ESP-IDF[63][64] – Espressif’s official IoT Development Framework for the ESP32, ESP32-S, ESP32-C and ESP32-H series of SoCs.
  • Arduino-ESP32[65] – Arduino core for the ESP32, ESP32-S2, ESP32-S3 and ESP32-C3.
  • Espruino – JavaScript SDK and firmware closely emulating Node.js
  • MicroPython (and CircuitPython) – lean implementation of Python 3 for microcontrollers
  • Lua Network/IoT toolkit for ESP32-Wrover[66]
  • Moddable SDK[67] - modern JavaScript and TypeScript with networking, graphics, and ECMA-419 [68] APIs
  • Mongoose OS – an operating system for connected products on microcontrollers; programmable with JavaScript or C. A recommended platform by Espressif Systems,[69] AWS IoT,[70] and Google Cloud IoT.[71]
  • mruby for the ESP32
  • NodeMCU – Lua-based firmware
  • PlatformIO[72]
  • Rust[73][74]
  • Visual Studio Code with the officially supported Espressif Integrated Development Framework (ESP-IDF) Extension[75]
  • Zerynth – Python for IoT and microcontrollers, including the ESP32
  • Matlab
  • Matlab Simulink
  • ESPHome — ESPHome is a system to control your ESP8266/ESP32 by simple yet powerful configuration files and control them remotely through home automation systems.

Reception and use

Commercial and industrial use of ESP32:

Use in commercial devices

  • Alibaba Group's IoT LED wristband, used by participants at the group's 2017 annual gathering. Each wristband operated as a "pixel", receiving commands for coordinated LED light control, allowing formation of a "live and wireless" screen.[76]
  • DingTalk's M1, a biometric attendance-tracking system.[77]
  • LIFX Mini, a series of remotely controllable, LED based light bulbs.[78]
  • Pium, a home fragrance and aromatherapy device.[79]
  • HardKernel's Odroid Go, an ESP32 based handheld gaming device kit made to commemorate Odroid's 10th anniversary.[80]
  • Playdate, a handheld video game console jointly developed by Panic Inc. and Teenage Engineering.
  • Octopus Energy Mini, an ESP32-C6 based real-time energy monitor.[81]

Use in industrial devices

  • TECHBASE's Moduino X series X1 and X2 modules are ESP32-WROVER / ESP32-WROVER-B based computers for industrial automation and monitoring, supporting digital inputs/outputs, analog inputs, and various computer networking interfaces.[82]
  • NORVI IIOT Industrial Devices with ESP32-WROVER / ESP32-WROVER-B SOC for industrial automation and monitoring with digital inputs, analog inputs, relay outputs and multiple communications interfaces. Supports LoRa and Nb-IoT as expansion modules.[83]
